Some Christians teach that Jesus was the first created being. Some Christians teach that Father alone existed in the beginning and Jesus was literally begotten by the Father into a new being.
Does Bible support those views?
Isa 48:12 Hearken unto me, O Jacob and Israel, my called; I am he; I am the first, I also am the last. (Emphasis by me)
The Old Testament God repeatedly claims that He is the first and He is the last. God created all things and nothing existed before God, hence He claims to be the first. Similarly everything is sustained by God. After Him there will be nothing hence He claims to be the last.
God alone can claim that He is first and last
In New Testament we see Jesus also making the same claim!
Rev 2:8 And unto the angel of the church in Smyrna write; These things saith the first and the last, which was dead, and is alive (Emphasize by me)
Jesus also repeatedly claims in New Testament that He is the first and last.
If God created Jesus or literally begot Jesus then Jesus cannot be First; at the maximum Jesus can be second.
By claiming to be first and the last just like God of the old testament, Jesus tells us that He co-existed with God from eternity without any beginning.
Let us see another verse which makes it very clear.
John 1:3 All things were made by him; and without him was not any thing made that was made.
It says all created things are created by Jesus. There is no created thing which is not created by Jesus. Logically it means Father did not create anything without Jesus; also logically Jesus is not a created being.
